' APPARATUS FOR TREATING HYDROCARBONS Filed Jan. 1a, 1928 Saw mawRBouxQ an vewboi Patented Apr. 18, 1933 PATEN SEWAIRD R. BOLLES, OF ELIZABETH, NEW JERSEY, ASSIGNOR TO S'IANDARD OIL DEVELOPMENT COMPANY, A CORPORATION OE DELAWARE APPARATUS FOB. REATING HYDROGABBONS Application filed. January 18, 1928.
This invention relates to the art'of distillation, more particularly to the fractional distillation of hydrocarbons and will be fully understood from the following description,
read in conjunction with the accompanying drawing: which is a vertical cross-section of a preferred embodiment of my invention.
Heated 011 and/or vapors from a pipe still, reaction chamber or other source, not
shown, are introduced into the vapor separating chamber 1 by the pipe 2. A. baffle 3 may be provided in chamber 1 to distribute the material introduced. Vapors separate from the body of liquid 4 in chamber 1 and are conducted by vapor line 5 to a bubble tower or fractionating column 6. The vapor separating chamber is also provided with the f usual draw-01f connection 1a for removal plates 7, provided with bubble caps 7 a, overflow pipes 7 Z), and an outlet 70 for removal of liquid from the tower if desired, and cool ing coil 8.
The fractionating column 6 is provided with a heater or reboiler indicated as a whole at 9 for heating the reflux condensate c01- lecting in the bottom of tower 6.
Vapors from tower 6 pass to a final condenser, not shown, by a vapor line 16 provided with a valve 16a for maintaining any desired pressure in the apparatus.
In the preferred form of my apparatus I Serial No. 247,517.
have shown a partial condensing such as a primary bubble tower, dephlegmator, or knockout box, schematically designated at 17, whereby-the vapors leaving the vapor separating chamber 1 may bev subjected to a preliminary separation before entering the tower-6. In case the primary fractionating means is used, valves 18, 19 in vapor line 5 are closed and valves 20,21 in vapor line 22, 23 are opened, thus directing the vapors through the primary separating means 17 As a practical example of my invention cracked hydrocarbon material, principally in vapor phase as produced'in crackingcoil operation, is delivered at a temperature of approximately 680 F. through pipe 2 to the vapor separating chamber 1, preferably maintained under a pressure of 50 lbs. gauge and in which separation takes place, producin a tar residuumandvapors- The tar resic uum is continuously or periodically drawn 0E through the valved pipe 1a. The vapors pass through-vapor line 5 and primary fractionator-17 to the bubble tower 6. The amount of cooling produced by coil 8 is controlled to produce an overhead vapor consisting substantially of gasoline fractions, which pass off through the valved vapor line 16.
i The condensate produced by the action of the coil 8 passesin a generally downward direction from plate toplate in countercurrent relationship to ascending vapors. Condensate collecting in the bottom of the tower 6 circulates down through the heater 9 where it is heated by the vapors and/ or liquid in the vapor separating chamber and returns thence to the tower. A. temperature of approximately 550 to 600 F. is maintained in the base of the tower. The reflux condensate collecting in the lower part of the primary fractionator 17 is withdrawn to any desired place. of disposal by valved pipe 17 a; Condensate in the base of tower 6 in excess of that necessary to maintain a predetermined liquid level therein iscontinuously or periodically withdrawn through the valved'pipe 7c.
It will of course be understood that the temperatures and pressure here given are merelyby way of illustration and that in different operations in which my invention may be used the temperatures and pressure will vary in accordance with the conditions of operation.
WVhile I have described my invention by reference to certain specific details, it will be understood that all changes are contemplated which come within the spirit and scope of the invention.
